Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.?
Yes, it is correct.
What is the difference between Iodine bought in a pharmacy and the Iodine stain solution?
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
What stain is used to test for plant starch in cells?
aqueous iodine in the form of potassium iodide turns purple in the presence of starches in water.
Why does an aqueous solution of iodine not react with potassium chloride?
because it dosent
Would you expect iodine to displace bromine form a solution of potassium bromide?
No. However, bromine would displace iodine in potassium iodide.
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
What is the equation of potassium bromide with aqueous iodine?
KBr + I2(aq) --> KBr + I2(aq) It does not react because bromine is more electronegative and reactive than iodine.
Potassium bromide is a stable molecule Iodine bromide is an unstable molecule Which statement explains the difference in stability?
Potassium bromide has ionic bonding, and iodine bromide has covalent bonding.
What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
What is the word equation for the reaction bromine and potassium iodide?
Bromine and Potassium iodide react to form Potassium bromide and Iodine.
Why doesn't potassium bromide react with iodine?
because it is gay
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.?
Yes, it is correct.
What are the differences between the compounds and elements that make potasssium iodide?
Potassium Iodide is made up of two elements : Potassium and Iodine. Potassium is a alkali metal while Iodine is non metallic and halogen. Potassium is strongly basic, while Iodine is strongly acidic. In this compound potassium is in +1 oxidation state, while iodine is in -1. Aqueous solution of Potassium Iodide can dissolve Iodine to make Potassium Tri-iodide, KI3, which is brownish in colour.
